Sample text

An attempt has been made to code the presence of all threatened species according to their occurrence in the three major biomes – terrestrial, inland waters and marine (Table 6). Where large numbers of aquatic species have been assessed, the proportion of threatened species rises markedly. The steep increase in the number of threatened marine birds compared to the figure of 61 given by WCMC (2000) is attributed to the increased number of albatrosses, petrels and penguins now included in the threatened categories.

The detailed country tables for all these taxa are included on the web site and the CD-ROM should the reader wish to explore them further.

For the purposes of this analysis the lower level threats in the hierarchy (see Annex 5) were grouped together to identify the major threats at the primary level and then two of the most important threats were further analysed to identify the specific threatening processes involved. As with the habitats analysis, a species can have more than one threat and so the values within a species group are non-exclusive. 27 Red List 2000 06 September 2000 16:14:54 Color profile: Generic CMYK printer profile Composite Default screen 2000 IUCN Red List of Threatened Species Habitat loss and degradation The results in Figure 9 show that the most pervasive and over-riding threat to birds, mammals and plants is habitat loss and degradation, affecting 89% of all threatened birds, 83% of the threatened mammals sampled and 91% of the threatened plants sampled.
